Another 10cm of snow yesterday has loaded the Jan 4 weak interface. Make good terrain decisions today, knowing this critical layer is reaching it's load limit.
Summary
Weather Forecast
Wednesday brings increasing cloud, scattered flurries, moderate SW winds at ridge-top, and freezing levels near valley bottom. As we head into Wednesday evening and Thursday, a strong system will push in, delivering moderate to heavy snowfall through Thursday afternoon. Expect 25-35cm of snow with strong SW winds and freezing levels near 1700m.
Snowpack Summary
Wind accompanied the 10cm of new snow yesterday, forming soft slabs in alpine and tree-line lee features. Below this new snow there is variable wind-effected snow in the alpine and settled, very soft slab at tree-line and below. Whumphing and cracking on the Jan 4 persistent weak layer, now buried 50-80cm, is still being reported.
Avalanche Summary
Poor visibility during the snowfall yesterday limited most observations. However, Macdonald Gully 3, a steep, planar N-facing alpine start-zone, kicked out a size 2.5 yesterday, covering most of the fan in the valley bottom. Otherwise, loose avalanches to size 1 were observed from steeper, rocky features.
Confidence
Due to the number of field observations
